1.1 Performance and features
√
With a CO P value up to 5.0 our heat pumps are very efficient w hen trans ferring heat from the air
to the s w imming pool w ater. You can s ave as much as 80% of cos t compared to an electrical
heater.
√
√
The heat exchanger is made of PVC and Titanium tube, which can withstand and prolong exposure
to swimming pool water.
The unit is very easy to operate: simply switch it on and set the desired pool water temperature.
The system includes a micro-computer controller, allowing all operation parameters to be set.
Operation status can be displayed on the controller with LED display.
1.2 Working principles
√
√
√
√
√
Heat pumps utilize the sun's free heat by collecting and abs orbing energy from the outs ide air. This energy
is then compressed and transferred to the pool w ater. Your exis ting w ater pump circulates the water
through the heater, usually next to the pool equipment, and the water warms up. The heat pump timer
could be set to operate during daylight hours, for example, usually 9am to 5pm.
The unit contains a fan that draws in outside air and directs it over the surface of the evaporator (energy
collector).The liquid refrigerant within the EVAPORATOR coil absorbs the heat from the outside air becomes
a gas.
The warm gas in the coil passes through the COMPRESSOR concentrating and increas ing the heat to form a
very hot gas which then passes to the CONDENSER (water heat exchanger).It is here that the heat exchange
occurs as the hot gas gives off heat to the cool swimming pool water circulating through the coil.
The pool water becomes warmer, and the hot gas cooling as it flow s through the CO N D EN S ER coilreturns to its liquid form and, after passing on through the CAPILLARY TUBE, the whole process begins
again.
The state of the heat pump technology can efficiently collect heat from the outside air down to the 7℃ to 10
range. For tropic and subtropical climates, this means that the pool can be maintained at 26℃ to 32℃.

2.4 Location of the swimming pool heat pump
The unit will perform well on any location provided three factors are present:
1. Fresh air supply
2. Electricity
3. Swimming pool filter piping
The unit may be installed virtually anywhere outdoors providing minimum distance requirements are met
with respect to other objects (see diagram below).For indoor pools please consult your installer. If the unit
is placed in a windy area, no problems occur with e.g. the pilot light, as opposed to what is often the case
with gas heaters.
Attention:
Do not place the unit in an enclosed area with a limited air volume where the unit's discharged air will be
re-circulated or near shrubs that could block the air inlet. These locations deny the unit a continuous fresh
air supply, which reduces its efficiency and may prevent adequate heat yield. See diagram below for
minimum required distances.
2.5 Distance from the pool
Normally, the pool heat pump is installed within a 7.5 meter radius of the pool. The greater the distance
from the pool, the greater the heat los s from the piping. S ince the piping is buried for the mos t part, heat
loss is minimal for distances of up to 30 meters (15 meters to and from the pump= 30 meters total), unless
the soil is wet or the water level is high. Heat loss per 30 meters could roughly be estimated at 0.6 kw hour (2000 BTU ) for every 5 ℃ temperature difference betw een the pool w ater and the s oil
surrounding the pipe, which translates to an operation time increase of 3-5%.
2.6 Installation of the check-valve
When using automatic chlorine and PH dosage systems, it is of uttermost importance to protect the heat
pump from high concentrations of these chemicals that could corrode the heat exchanger. Therefore, such
systems should add the chemicals in the conduits located downstream of the heat pump and it is
recommended to install a check-valve in order to prevent backflow when there is no water circulation.
Damage to the heat pump caused by disregarding any of these recommendations will invalidate the
warranty.
2.7 Pool system set-up
Ensure that the heat pump is installed above the pool level. Please make sure that it is possible for the
water to run out of the heat pump automatically when the circulation pump is switched off, because then
the flow switch will turn of the heat pump. When the heat pump continues running without any flow it
could cause enduring errors and or damage you heat pump.
2.8 Connecting the by-pass
In order to regulate the heat pump’s water circuit, you must provide a by-pass between the incoming and
outgoing connections. Therefore the piping must feature three regulation-valves according to the below
diagram.

2.9 Electrical hook-up
IMPORTANT!
Although the heat pump is electrically isolated from the rest of the unit, this only prevents the passage of electricity to or from the
pool water. Grounding the unit is still required to protect yourself from short circuits inside the unit. Please contact a certified
electrician to make sure your heat pump is grounded correctly..
For horizontal models (VBK / ZWPT / ZWPA) the electrical connection area is located behind the cover on the right side next to the
fan opening.
Connect the electrical wires with the terminal block labelled “Power Supply”. Next to this connection, there is a second terminal
block labelled “Water Pump”,to which the filter pump (max . 5A/240V) can be connected. This connection makes it possible to
control filter pump operation with the heat pump. See further at Parameter setting table (Parameter 9) for the different
possibilities.
Remarks for models with 3 phases:
for models with 3 phases, switching 2 phases may cause in inversion in the rotational direction of electrical motors, which could
damage the unit. Therefore, a protection device has been built in, which will interrupt the circuit if the connection has not been
performed correctly.

3.1 Starting up the heat pump (first-time)
Attention!
In order for the unit to heat the pool (or spa), the filter pump must be running so that the water can
circulate through the heat pump. Without this circulation, the heat pump will not start.
When all connections have been made and checked, you should follow these steps:
√
Turn on the filter pump. Check for leaks and verify flow to and from the pool.
√
Turn on the electrical power supply to the unit, then press the ON/ OFF key on the electronic
control panel. The unit should start when the time delay period has lapsed.
√
When the unit has been running for a couple of minutes, check if the air leaving the unit is cooler.
√
Check the performance of the flow switch as follows: with the unit running, turn the filter pump off.
The unit should also switch off automatically. If not, the flow switch must be readjusted.
√
All the unit and filter pump to run 24 hours a day until the desired pool water temperature is
reached. When the set temperature is reached, the unit switches itself off. The unit will now
automatically restart (as long as your filter pump is running) when the temperature of the pool
water experiences a drop of more than 1℃ below the set temperature.
Depending on the starting temperature of the pool water and the air temperature, it can take several days
for the water to reach the desired temperature. Covering the pool can drastically reduced this period.
Water Flow Switch
The unit is equipped with a flow switch that is switched on when enough water has
flowed through the unit and that is switched off when the water flow becomes too low. (For example when
the filter pump is switched off).
Time delay
The unit is equipped with a built-in 3-minute s tart delay included to protect electrical
components and contacts. After this time delay, the unit will automatically be restarted. Even a brief
interruption of the pow er supply will activate the s tart delay and prevent the unit from s tarting
immediately. Additional interruptions of the power supply during the delay period will have no effect on
the 3-minute countdown.
Condensation
When the swimming pool water is being heated by the heat pump, the incoming air is cooled down quite a
bit, which can cause condensation on the fins of the evaporator. Condensed volumes can attain several
liters per hour under high atmospheric humidity. Sometimes, this is wrongfully interpreted as a water leak.
4.1 Controlling the heat pump with the LED controller

5.1 Protection systems
Water flow switch
Equipped w ith flow s w itch the heat pump w ill not w ork w hen the filter pump is not w orking (and the
water is not circulating). This system prevents the heat pump from heating only the water present in the
heat pump itself. The protection also stops the heat pump if water circulation is cut off or stopped.
Refrigerant gas high and low pressure protection
The high pressure protection makes sure the heat pump is not damaged in case of over pressurisation of
the gas. The low pressure protection emits a signal when refrigerant is escaping from the conduits and the
unit can not be kept running.
Overheating protection on the compressor
This protection protects the compressor from overheating.
Automatic defrost control
When the air is very humid and cold, ice can form on the evaporator. In that event, a thin layer of ice
appears that will grow increasingly bigger as long as the heat pump is running. When the temperature of
the evaporator has become too low, automatic defrost control will be activated, which will reverse the heat
pump cycle so that hot refrigerant gas is sent through the evaporator during a brief period of time to
defrost it.
Temperature difference between inflowing and outflowing water
During normal operation of the heat pump, the temperature difference between inflowing and outflowing
water will approximate 1 to 2℃.In the event that the pressure switch does not work and that the water
stops circulating, the temperature probe monitoring the outflowing water will always detect a rise in
temperature. As soon as the temperature difference between inflowing and outflowing water exceeds
13℃, the heat pump will be automatically turned off.
Low temperature cut-out
If, during cooling, the temperature of the outflowing water reaches 5℃ or drops below this temperature,
the heat pump will turn itself off until the water temperature reaches or exceeds 7℃ again.
Anti-frost protection during winter
This protection can only be activated if the heat pump is in STAND-BY status.
First anti-frost protection (switching external water filter pump)
If the filter pump is controlled by the heat pump (regardless of the value for parameter 9) and when the
water temperature lies between 2 and 4℃,and the air temperature is lower than 0℃,the filter pump will be
automatically turned on to prevent the water from freezing in the piping. This protection is deactivated
when the temperature rises again.
Second anti-frost protection
If the water temperature drops even more, that is, below 2℃ (during long frost periods), the heat pump will
also start running to heat the water until its temperature approximates 3℃.When this temperature is
reached, the heat pump will stop, but anti-frost protection will remain active until conditions change.
ATTENTION!
The first anti-frost protection is only available when the external water pump is switched by the heat pump.
If the external water pump is not operated by the heat pump it should always be on.
5.2 Swimming pool water chemistry
Special attention should be paid to the chemical balance of the pool water. The pool water values should
always stay within the following limits:
Important: failure to comply with these limits will invalidate the warranty.
Note: exceeding one or several limits can damage the heat pump beyond repair. Always install water
treatment equipment past the heat pump's water outlet, especially if the chemicals are automatically
added to the water. A check-valve should also be installed between the outlet of the heat pump and this
equipment in order to prevent products from flowing back into the heat pump if the filter pump stops.
6.1 Heat pump winterizing
Important: failure to take the necessary precautions for winterizing can damage the heat pump, which
will invalidate the warranty.
The heat pump, filter pump, filter and conduits must be protected in areas where the temperature can drop
below the freezing point, Evacuate all water from the heat pump as follows:
√
√
√
√
√
Interrupt the electrical power supply to the heat pump
Close the water supply to the heat pump
Completely close valves 2 and 3 of the by-pass
Disconnect the water inlet and outlet coupler fittings of the heat pump and let the water drain out
of the unit.
Loosely reattach water inlet and outlet coupler fittings to the heat pump in order to prevent dirt
from setting into the conduits.
6.2 Restarting the pump after winter
If you purged your heat pump for winterizing, you should undertake the following steps to restart it in
spring:
√
√
√
√
Check first if there is no dirt in the conduits and if there are no structural problems
Check if the water inlet and outlet coupler fittings are adequately fastened to the heat pump
Start the filter pump to start the water flow to the heat pump. Set the by-pass again
Reconnect the electrical power supply to the heat pump and turn it ON.
6.3 Check-up
Our heat pumps have been developed and built to last, that is, if they have been installed correctly and can
run under normal conditions . Regular check-ups are important if you w ant your heat pump to function
safely and efficiently for years on end.
√
Make for easy access to the service panel
√
Keep the area surrounding the heat pump free of contingent organic waste
√
Prune the vegetation near the heat pump so that there is enough free space around the pump
√
Remove contingent water sprinklers from the vicinity of the heat pump. They can damage the heat
pump.
√
Prevent rain from directly running off a roof onto the heat pump. Install proper drainage
√
Do not use the heat pump if it has been flooded. Immediately contact a qualified technician to
inspect the heat pump and repair it if should prove necessary
Condensation can occur when the heat pump is running. This condensation can flow away through an
opening in the base pan of the unit. The amount of condensation water will increase when atmospheric
humidity is high. Remove any dirt that could possibly hamper the evacuation of condensation. 10 to 20
litres of condensation water can be produced while the unit is running. If more condensation is produced,
stop the heat pump and wait for one hour before checking for leaks in the conduits.
Note: a quick way to verify that the water running through the condensation drain is indeed condensation,
is to shut off the unit and keep the pool pump running. If the water stops running out of the condensation
drain, it is condensation. AN EVEN QUICKER WAY is to TEST THE DRAIN WATER FOR CHLORINE. If no
chlorine is detected, the drain water is a result of condensation.
Also take care to leave air inlet and exhaust passages free. Prevent exhaust air from immediately reentering the unit through the inlet.

No electrical power supply
Check power supply (wiring, fuses,… …… …)
Problem:
the heat pump works normally but there is no or insufficient heating
Observation:
The screen displays the temperature but no error codes
Possible cause
Solution
1. In sufficient capacity of the heat pump in proportion to the
size of the swimming pool
1. Install a larger sized model or an extra heat pump.
Cover the pool to limit heat loss
2. The compressor works but the fan doesn't
2. Check the electrical wiring of the fan. Replace the
condenser or the fan motor if necessary.
3. The fan works but the compressor doesn't
3. Check the electrical wiring of the compressor.
Replace the condenser or the compressor if necessary.
4. The heat pump has not been placed on an optimal location
4. Make for sufficient air circulation(see manual for
details)
5. Faulty temperature setting
6. By-pass not adjusted
7. Massive ice formation on the evaporator
8. Not enough refrigerant
5. Set the correct temperature
6. Have the by-pass readjusted by the installer
7. Have the settings for automatic defrost control
checked by the installer
8. Have the heat pump checked by a refrigeration
technician
Problem:
The heat pump works normally but the water is cooling down instead of heating up
Observation:
The screen displays the temperature but no error codes
Possible cause
1.The wrong mode has been selected
2. The controller is out of order
3. The 4-way valve is out of order
Solution
1.Verify the parameters, select the correct mode
2. Check the voltage in the electrical wiring to the
4-way valve. If no electric potential is measured,
replace the controller
3. Check the voltage in the electrical wiring to the
4-way valve. If electric potential is measured,
replace the coil. If the problem persists, have the
heat pump checked by a refrigeration technician
Problem:
the heat pump doesn't stop
Observation:
the screen displays the temperature but no error codes
Possible cause
Solution
1.Wrong setting of parameters
2. Pressure switch out of order
3. Electrical failure
1.Check the set parameters and adjust them if necessary
(settings just above the capacity of the heat pump)
2. Check operation of the pressure switch by turning
off the filter pump and restarting it. If the heat pump
doesn't react to this, the pressure switch must be
adjusted or replaced.
3. Contact your installer
Problem:
water leak
Observation:
there's an amount of water under the heat pump
Possible cause
Solution
1.Condensation due to atmospheric humidity
1.No action required
2.Water leak
2.Try to localize the leak and check for the presence
of chlorine in the water. If that is the case, the heat
pump must be temporarily replaced during repair.
Problem:
abnormal amount of ice formed on the evaporator
Observation:
the evaporator is for the most part covered in ice
Possible cause
1.Insufficient air inflow
2.High water temperature
3.Incorrect setting of automatic defrost control
